Was wondering if any one blues there makers mark so the the letters are darker. i some times stamp but most of the time i mount the blade in the cnc mill and mill in my name. but i was thinking of bluing the letters and polishing the blade so just the letters are dark. any ideas
 
maybe there is a way of applying a resist to the flats of the blade and AC etching it?
 
well i have a liquid blue that you just brush on and its like instent blue. just wondering how it would look
 
I think that would be fine. Heck you could even just rub some brown mustard into the stamp and let it sit for a bit. Not going to work on stainless, of course.

JT it's funny you should post this now...the other day I was testing out my stamp and wondered the same thing. I applied some blue layout dye, then sanded over the mark to remove the excess. It certainly made the mark more visible, but how long the layout dye will last in there is questionable, since it doesn't really penetrate like cold blue does. It's the only avenue I've explored with this so far. -Matt-
 
Very simple....I do all my marks like this. I etch my mark, and I like to do it deep. When I'm done with the etch I clean it all out with some alcohol then dab in some cold blue. Hit it with some windex...wipe down then hit w/ wd-40.
I have my blade just about all hand sanded out when I do the etch. After the bluing I do my final sanding. It makes the mark stand out great!

OK here are my test results. I am very very happy with how it turned out. nice and dark letters that are durable and wont rub off. sorry about the sample keychain looking crappy quality but that's what happens when you only have 3 fingers to use to make something

I will get you the name of the blue stuff i used, it was fast just brush t on and bam it was blued.
 
I've used Birchwood-Caseys Perma Blue, it works like you describe. They have a Super Blue I haven't tried. They also sell Brass Black which could be neat to darken filework on guards, etc. It works about the same as the blue in practice.
 
I just polish my etched mark with flitz or mothers mag polish and the black junk from polishing fills the etch and stays black.
